  • What are the most common applications for VectorNav products?

    The VN-100, VN-200 and VN-300 can be used in a wide variety of commercial, industrial, aerospace and military applications and are well suited for size, weight, power and cost (SWAP-C) constrained applications such as UAVs and other unmanned vehicle systems, camera/antenna and platform stabilization, smart weapons, heavy machinery monitoring, robotics, primary or secondary flight navigation, flight simulation, and augmented/virtual reality platforms, among others.

    The VN-100 and VN-200 surface mount modules are highly attractive for customers looking to deeply embed a navigation solution into their electronics design/PCB. This option allows for the user to customize and design their products around a sensor with a very small footprint. Alternatively, the VN-100, VN-200 and VN-300 Rugged offer an off-the-shelf solution for faster integration and environmental robustness.

  • Can VectorNav sensors be used in the Antenna Tracking / Pointing applications?

    The VN-200 and VN-300 are well suited for a variety of platform stabilization applications. The VN-200 GPS-aided inertial navigation algorithm is capable of compensating for dynamic acceleration induced from the motion of vessels or ground vehicles while maintaining accurate attitude measurements. With a full filter state update rate of up to 400 Hz, the VN-200 provides extremely low latency attitude and angular rate measurements, which are critical for closed-loop control.

    The VN-300 is especially well suited for platform and antenna tracking applications that experience little or no dynamics. The VN-300 dual GPS antenna uses GPS interferometry (GPS compass) techniques, which allow for the device to compute heading using two GPS antennas. This allows the VN-300 to provide accurate heading measurements in both dynamic and static operating conditions.

    Maritime VSAT satellite communications require stabilized antennas that remain pointed at the satellite in order to ensure continuous data transmittal. Regulations often require that pointing accuracies remain better than 1 degree to maintain active transmission. The VN-200 and VN-300 satisfy this requirement for highly accurate, precise and low latency attitude and angular rate measurements. They are also able to counter low frequency acceleration and vibration disturbances to actively stabilize platforms where precise orientation feedback is required.

  • Can VectorNav sensors be used in Camera Stabilization or Aerial Imaging applications?

    The repeatability and low latency of the IMU measurements on each of the VN-100, VN-200 and VN-300 make them well suited for airborne camera and antenna stabilization applications. The VN-200 and VN-300 provide the added benefit of geo-referenced measurements for applications with absolute pointing requirements.

    Utilizing the GPS and pressure sensor measurements together with the inertial sensor measurements, the INS algorithm onboard the VN-200 and VN-300 estimate absolute heading to better than 0.3 degrees with respect to True North and 0.1 degrees in pitch and roll in dynamic environments.

    For camera stabilization and aerial imaging applications that experience intervals of low dynamics or static conditions, such as those experienced on camera payloads onboard helicopters and multi-rotors, the VN-300 provides the added ability of providing accurate heading and attitude measurements in these scenarios.

  • Can VectorNav sensors be used in Unmanned Aerial Vehicles (UAVs)?

    The VN-200 and VN-300 are commonly used for autonomous control of unmanned aerial platforms. With update rates of up to 400 Hz (1 KHz IMU update rates on custom firmware), high bandwidth, low-latency position and attitude measurements can be directly connected to the necessary control loops. The VN-200 and VN-300 calibration procedures ensure a high accuracy pitch and roll solution relative to the horizon while the on-board barometric pressure sensors provide autonomous aircraft with greater ability to precisely hold altitude. Each of the VN-100, VN-200 and VN-300 can cope with very high accelerations during launch and cornering. The small size, weight and power requirements provide for the ability for the onboard systems and payloads to take on additional weight.

    UAVs and other unmanned aerial system manufacturers often use COTS gyros, accelerometers, magnetometers and GPS modules to provide for navigation of their UAV systems. In these cases customers often write custom filters to fuse these measurements and provide for navigation of the system. The VN-100, VN-200 and VN-300 onboard filters incorporate the state-of-the-art, aerospace grade digital filtering techniques, while maintaining a highly flexible framework that allows for the incorporation of outside measurements and a wide degree of customization options and features. The advanced calibration of the individual components onboard each VectorNav sensor provide additional improvement in performance independent of variations in temperature.

  • Can VectorNav sensors be used in Missiles, Guided Munitions and Military Systems applications?

    VectorNav has experience in the design, development and integration of inertial sensing systems for guided munitions and other missile applications. The small SWAP requirements of the VN-100, VN-200 and VN-300 are critical for these types of applications and are well suited for high-shock environments. Custom hardware and filter development is often required for these types of systems and the VectorNav Applications Engineering team is often a key asset in assisting customers to produce these systems.

  • Can VectorNav sensors be used in Robotics applications?

    Ground-based robotic vehicles operate in a wide range of environments where magnetic interference often makes heading determination difficult. The VN-100 utilizes proprietary adaptive filtering and disturbance rejection algorithms which provide more accurate and stable heading measurements when magnetic interference is present. The impact of vibration and magnetic disturbances from nearby electric motors can be minimized utilizing the on-board adaptive filtering capabilities provided by the onboard Vector Processing Engine.

    For users that require a higher degree of heading accuracy for these applications, the VN-300 Dual Antenna GPS/INS uses GPS interferometry (GPS compass) techniques, which allow for the device to compute heading using two GPS antennas. This allows the VN-300 to provide accurate heading measurements in static operating conditions, without reliance on the magnetometer.

  • What are the other applications that can utilize VectorNav sensors?

    Heavy Machinery / Agriculture

    Excellent shock resistance and survivability make the VN-100 well suited for heavy machinery performance monitoring applications and can serve as an alternative to encoders that require a direct linkage to the moving members. VectorNav has a number of customers using the VN-100 for this application where the VN-100s have been operating in-field, under daily loads for several years without failures.

    Dead Reckoning

    Customers with indoor applications or cave-mapping applications often seek to use the VN-100 as a dead-reckoning device. By integrating the accelerometers to derive displacement, positioning information can be obtained with the VN-100, however, without the assistance of GPS or other positioning system, position estimates obtained by integrating linear accelerations experience unbounded error growth. Even after calibration, residual biases and axis misalignments in the accelerometer measurements will quickly grow position estimate errors. For example, industrial-grade accelerometers, such as those built-into the VN-100, can yield errors on the order of 50 meters in just 60 seconds. If measurements from an indoor positioning system are available, VectorNav can provide custom filters for an indoor INS system.

    Deep Bore Drilling / Pipeline Mapping

    Customers often inquire about the suitability of the VN-100 for deep bore drilling or pipeline mapping applications. The aim is usually to track heading, orientation or position to help operators maintain a drilling direction or to map out a previously laid pipeline or borehole. It can be difficult to discern the Earth’s background magnetic field from disturbances in the surrounding environment, where there are long sections of pipeline encased in steel for example, which results in unreliable heading estimates. Gyroscopes of significantly better accuracies (and expense) as well as high operational temperature instruments used in the oil and gas field are usually required to maintain required performance (generally referred to as Measurement While Drilling). Mapping of existing holes of significantly shorter length might be possible with the VN-100 gyroscopes; however, VectorNav does not have any direct experience to comment on accuracies or requirements for maximum operation time. It is possible for VectorNav to develop custom solutions that incorporate external measurements of length of wire/sections of pipeline to bound position estimate errors or incorporate higher accuracy gyros for gyro-compassed heading measurements.

    Gait Measurement

    Customers attempt to fuse measurements from a VN-100, VN-200 or VN-300 and other sources to determine motion of a foot or other body part to obtain distance traveled or indoor position. For example, a developer of such a system may use the pause in motion experienced when a person’s foot is planted to the floor to apply this information to improve positioning estimates. Other kinematic constraints can be applied to further support the position or displacement measurements; however such systems suffer from the same errors.

  • What are the advantages of using VectorNav products compared to other inertial/navigation sensors?
